Despite Soviet secretiveness, the membership of the cosmonaut corps and how it changed with time is fairly well known; there are no unaccounted-for cosmonauts. For a while there were, but it turns out that they left the program in quite mundane ways, mostly plane crashes (still the leading cause of death among US astronauts) and medical problems, with one or two major disciplinary infractions thrown in. Claims of secret Soviet space failures do not appear to have any solid evidence behind them. (What they do have behind them, quite possibly, is a deep-seated wish to show the Soviet program as incompetent and wasteful of human life. As compared to the awe-inspiring competence and caution of the US program, of course. :-( ) -- NASA is to spaceflight as the | Henry Spencer at U of Toronto Zoology US government is to freedom. | uunet!attcan!utzoo!henry henry@zoo.toronto.edu ------------------------------ Date: 26 Jun 89 08:45:38 GMT From: att!occrsh!uokmax!metnet!p3.f30.n147.z1.FIDONET.ORG!Greg.Trotter@ucbvax.Berkeley.EDU (Greg Trotter) Subject: Re: Don't mess with NASA?

Astronaut Stanley David Griggs died when his light plane crashed while he was possibly performing stunt maneuvers on June 18, 1989. Griggs, who joined the astronaut corps in August 1978, was scheduled to pilot the STS-33 mission on DISCOVERY for this fall. His only space mission was on Space Shuttle 51D on April 12, 1985 on DISCOVERY. He was a mission specialist on that mission, which included U.S. Senator Jake Garn.

You are looking for `The Astronomical Almanac' jointly published annually in both the U.K. and the U.S.. In the U.S. it comes from the USNO and you should be able to find copies in every university library where astronomy is taught. It's the definitive source for this kind of data. From memory there is a section which gives heliocentric coordinates and velocities for all the planets in cartesian form. For multiple dates, look in several successive year's AA. Do the satellites as separate problems from a planet centered point of view. Starting conditions for these will be harder to come by: you'll have to calculate them yourself from orbital data in another form I think. >Seems simple enough.

Hopefully this is all that's required to model our >system accurately, however, with all their finding out about chaotic phenomenon >in orbits, who knows. In principle it is simple but unless you know some numerical integration theory, watch out. Up until a few years ago, the AA was based on other methods for most objects but recently I understand it has changed to numerical integration almost entirely. Accordingly a new `Explanatory Supplement' has been in preparation for some years which I eagerly await. You may find the old `Explanatory Supplement' useful and it should be found in the same places as the AA. >I would imagine JPL uses something like this to figure out where their probes >are going, maybe someone there could help. I believe JPL is indeed the place where many of the calculations for the AA are done. Good luck.

Internet: tneff@bfmny0.UU.NET I applaud your proposal to set ourselves the goal of a base on Mars by 2040, although I don't think it's reasonable next step (why try to work out the bugs of living in an esentially hostile environment when it takes help anywhere from months to years to get there, why not get the bugs worked out on the moon first?) But I would cation against having excitement and adventure as the only major motivating force. James Burke, technological historian, in the concluding show of his television series _Connections_, talked about the apollo mission. He talked about the time he covered the apollo 11 liftoff. He said, "It was an emotional day for all of us, I won't forget it! The problem is that that rocket took off as much on euphoria as rocket fuel. The public saw it as a great adventure, and how many great adventures are you willing to pay for when the plot is always the same? And so, after 7 missions, the program was canceled-- but before you say, 'good, waste of money', in the same period of time, american women spent the same amount on cosmetics. It was lack of understanding of the scientific reasons behind apollo that killed it." (I'm did my best to recall that from memory, but I may not have gotten it exactly) There are many dangers with hoping for euphoria to carry you all the way to Mars and 2040. If any goals are to be set, they have to be closer than either Mars or 2040. (Even I will be an old man of 72 by the time I see 2040, if I ever do) and the public should be at least partially what we hope to learn by this little adventure, and how we plan to learn it. -- Gandalf (a.k.a.

OK, it was posted on rec.ham-radio by watmath!mcvax!mike; I don't recall the date of the original post, as it's in the paper archives and not the magnetic ones, and I don't have the time to dig it out. Eric Roskos (roskos@cs.ida.org) made a similar posting, including a MacWrite schematic, also in rec.ham-radio; his posting appeared here on 9 April, with the header slightly munged so I don't have the actual poting date.

The parachute on Soyuz 1 failed to open and there was some sort of leak in the hatch mechanism of Soyuz 11 which resulted in the cosmonauts asphyxiating before re-entry. These are well-documented and were not covered up. This being the case, I don't think any of those "missing" Vostok or Voskhod missions are very likely. But the people who put together that fact sheet had to have gotten their stories from somewheres (ie, there might be a grain of truth to this). What are the sources of this information? Has glasnost opened up some of the old Soviet space files (which probably contain some very interesting information, even if they aren't covering up any deaths, like the details of their proposed moon mission)? I used to know a lot about early space missions but I'd lost interest a few years back. I may do a bit of independent research into this if someone can point me in the right direction.
